I've had occasion to want to be able to load the ucom driver while customizi= ng=20 how it attaches devices. Especially, I have the Qualcomm 5220 EVDO modem ca= rd=20 in mind, which can function as a USB serial device but does not make itself=20 known as a generic serial device. It happens that Linux can use its stock=20 serial USB driver for the 5220 by loading it with some parameters... =20 modprobe usbserial vendor=3D0xf3d product=3D0x0112 ...that direct the driver to attach a specified vendor/product. It's not apparent to me that FreeBSD has a comparable feature for its USB=20 drivers (or ucom in particular). In fact, there isn't any way (well, not=20 mentioned on the kldload man page) to pass parameters of any kind to ucom. How would one solve this problem in FreeBSD? Would one have to create a new= ,=20 specialized USB driver that works in concert with the ucom device driver aft= er=20 the fashion of the uplcom or umct drivers?
